EAVES-TROUGH.

To all whom it may concern:

Be itI known that I, PHILLIPP F. FLAGGE, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofIVisconsin, have invented certain new and useful Improvement-s in Eaves-Troughs, of which the following is a speciication, reference being hadto the accompanying drawing, forming a part thereof.

This invention relates to sheet metal eavestroughs and its main objectsare to stiften one or both edges of the trough, to preventthe troughfrom warping, winding or twisting and from spreading or opening, toeconomize in material used in the construction of the trough, andgenerally to improve the construction of eavestroughs of this class.

It consists in a trough having one or both edges transversely crimped orfiuted either at rightangles or oblique thereto.

In the accompanying drawing like characters designate the same parts inthe several figures.

Figure 1 is a perspective view of a short section or length ofeavestrough embodying the invention in its preferred form; Fig. 2 is anend elevation of the same; Fig. 3 is a `perspective view of a. modifiedform showing a section of trough having both edges crimped; and Fig. 4is an end elevation of the same. l

Referring to Figs. l and 2, showing the invention as embodied in thepreferred form, a designates a short section of sheet metal eavestroughformed on the outer side with a marginal stitfening bead or roll l) of acommon form. vAlong the inner side which is placed next to a building,it is formed with a transversely crimped or fluted stifening edge o, thecrimps or flutes extending through and some distance below the edge,either at right angles thereto, as shown, or oblique thereto. Along theline -of union or junction between the corrugated and .non-corrugated orplain portion of the trough the bend or deflection of the metalSpecication of Letters Patent.

the trough at and adjacent to its inner edge and prevents the troughfrom windin warping or twisting, and tends' to prevent it from spreadingor opening not only during the process of construction, but after it ismade and is put up on a building. It also admits of the use ofcomparatively light or thin sheet metal in the construction of thetrough which is made in long lengths' or sections, and effects aconsiderable savin lin material as compared with trough provided withbeads or rolls on one' or' both edges, each head or roll taking upconsiderable metal and requiring blanks of greater width.

The bead or roll b on the outer side of the trough serves notonly. tosti'en and strengthen it, but gives it a finished appearance where it ismost exposed to view. The trough may however, be formed on both sides,as shown in Figs. 3 and 4, with transversely crimpedor flutedstifi'ening edges c, the crimping or fiuting of the outer edge takingthe place of the bead or roll b.

I claim:

1. A4 sheet metal eavestrough` having a transversely crimped stiieningedge. Y

2. A sheet metal eavestrough formed with transverse stiii'ening crimpsextending downwardly from and terminating slightly belowr one edgethereof.

3. A sheet metal eavestrough having tiansversely crimped or flutedstitfening e ges.

In witness whereof I hereto aiiix my sig' nature in presence of twowitnesses.
